Re: Iron Bull tarot card won't change

There is a final romance scene with him that triggers both the achievement and card change. For some people it's bugged and won't become available (like me, sad day.) For others it works just fine. Try talking to him again and see if you get an extra option under "let's talk about you and me." the option should say something along the lines of "Let's spend some time together." or somethin'. It'll trigger the last scene and his card will change.
